====== DIRAC ======

===== Warning for DIRAC users =====

Users running the DIRAC RELCCSD module should be aware that they must use the following configuration in their inputs:

<code>
**RELCC
.INTERFACE
DIRAC6
</code>

If they also use the MOLTRA module in their CCSD (or CCSD(T) or FSCC) calculations, they **must** also add the following lines:

<code>
**MOLTRA
.SCHEME
6
.HTSORT
1
</code>

Given the high data transfer load that the current (since DIRAC-23.0) default scheme (SCHEME4) implies in Hábrók, we ask all DIRAC users who use these features to include the aforementioned variables in their input files. More information can be found [[https://www.diracprogram.org/doc/master/manual/moltra.html#scheme|here]] and [[https://www.diracprogram.org/doc/master/manual/moltra.html#htsort|here]].
